Softliss International Professional 3-Step System Kit – Clarifying Shampoo, Diamond Plus Treatment & Sealing Mask
Experience the complete SL International professional hair transformation system, designed to deliver salon-quality straightening, reconstruction, and lasting shine in three expertly formulated steps. This professional kit combines everything needed for a full treatment protocol, from deep cleansing to intensive straightening and reconstruction, followed by final sealing.
Step 1 – Clarifying Shampoo: A professional deep-cleansing formula that removes product build-up, excess oils, and residue, preparing the hair to fully absorb the treatment that follows.
Step 2 – Diamond Plus Treatment: An intensive straightening and hair regeneration Capillary Suerum, formulated for thick, very curly, and damaged hair that requires deep nourishment, structural repair, and extreme smoothness. It delivers ultimate shine and reconstruction, restoring strength and manageability to resistant, coarse hair.
Step 3 – Sealing Mask: A deep-hydrating and sealing treatment that locks in the results of the previous steps, closing the hair cuticle and delivering intense nourishment, protection, and lasting shine.
Together, these three professional formulas work in sequence to transform thick, resistant, or damaged hair into smooth, straightened, healthy, radiant hair with results that last. Formulated exclusively for professional salon use, this complete system ensures optimal results at every stage of the treatment.
